実験手順

In a closed vessel compound 20 (300 mg, 0.600 mmol) is dissolved in MeOH, HCl (0.045 ml, 0.180 mmol) in dioxane is added and the mixture is stirred at room temperature for 10 days, then further HCl (0.045 ml, 0.180 mmol) is added and the reaction mixture is stirred for further 2 days. The reaction mixture is concentrated to dryness affording the title compound (253 mg, 0.600 mmol, 100% yield).

後処理

  1. stirringthe reaction mixture is stirred for further 2 days
  2. concentrationThe reaction mixture is concentrated to dryness
